Revenue drivers

• Allegion Americas — The larger segment, covering non-residential and residential security products and access control in the U.S. and Canada; in Q2 2026 Americas revenues rose 11.8% (8.9% organic) and adjusted operating margin was 30.1%.
• Allegion International — Primarily European security and access control businesses including CISA, Interflex, SimonsVoss, Bricard and ELATEC; Q2 2026 revenues rose 16.2% on a reported basis but declined 1.2% organically, with adjusted operating margin of 12.4%.
• Electronic security and access control — Electronic locks, credential readers, access control systems and software including cloud and Bluetooth Low Energy products; management calls strong demand for electronic security a long-term growth driver.
• Door controls, doors and accessories — Mechanical and automatic door hardware, hollow metal doors and frames, glass systems and related components sold under brands such as LCN, Von Duprin, Steelcraft, Republic, TGP and Falcon.

Recent performance

Q2 2026 net revenues were $1,151.5 million, up 12.7% year over year, comprising 3.3% pricing, 3.6% volume, 5.1% from acquisitions/divestitures and a 0.7% currency tailwind. Organic revenue growth was 6.9%, led by the Americas. Q2 2026 net earnings were $184.6 million, or $2.15 per diluted share, versus $159.7 million and $1.85 in Q2 2025; adjusted EPS was $2.40, up 17.6%. Operating margin was 22.1% (adjusted 24.2%) versus 21.5% (adjusted 23.7%).

Strategy

Allegion is pursuing growth through both mechanical and electronic product portfolios plus complementary software and services. It has been an active acquirer: 2025 acquisitions including ELATEC totaled approximately $631.6 million of consideration, and in March 2026 it acquired Door Components, Inc. for approximately $70 million, reported in Allegion Americas. It is expanding electronics and access control in attractive end markets and increasing strategic channel relationships. It returns capital through dividends, paying $1.10 per share in the first half of 2026, and repurchased approximately 1.2 million shares for $160.6 million in that period. It also amended its revolving credit facility in December 2025, increasing commitments to $1.0 billion and extending maturity to 2030.

Risks

• Tariff and trade exposure — Allegion estimates it sources roughly 20-25% of COGS from Mexico, under 5% from China and 5-10% from other non-U.S. countries, leaving it exposed to shifting tariff regimes despite pricing offsets.
• Construction market cyclicality — Demand depends on institutional, commercial and residential construction and remodeling markets, which are cyclical and sensitive to credit availability, government spending and work-from-home trends.
• European demand weakness — International organic revenue declined 1.2% in Q2 2026 due to weaker demand in core European markets, pressuring segment margin.
• Acquisition integration and margin dilution — Acquisitions contributed 5.1% to Q2 2026 revenue growth but were a 40-basis-point headwind to Americas adjusted operating margin.

Outlook

Management raised its full-year 2026 outlook for revenue and adjusted EPS after Q2 results. It cites continued strength in the Americas non-residential business and positive demand indicators entering the second half of 2026. For Allegion International, management points to weaker demand in some European markets and says the team is focused on execution and cost discipline. Tariff refunds from IEEPA claims remain uncertain in amount and timing, and no recoveries have been recorded as of June 30, 2026.
